Essex-based County Broadband has witnessed a five-fold increase in its workforce so far this year, up from 16 to 60 since the start of 2019 with expectations of a 79-strong team by the end of December.
New roles in technology, finance and community engagement have been created as part of the business expansion.
It follows a £46m private investment from Aviva Investors in 2018 to support the firm’s rollout of hyperfast full fibre broadband to rural areas in East Anglia.
Lewis Simington, Human Resources Manager, said: “We have just launched a seven-year business plan and 2020 will be the year when we really start coming into our own.
“The ambition is to become a major player, both in the region and in the national technology sector."
County Broadband aims to provide connection access to around 40,000 premises by the end of 2020.
